CAR-TRUCK SIDE FRAME.

Application filed December 4, 1913.

To all whom it may concern Be it known that I, WILLIAM D. Fon- SYTH, acitizen of the United States, residing at Youngstown, in the county ofMahoning and State of Ohio, have invented a new and useful Improvementin Car-Truck Side Frames, of which the following is a specification.

This invention relates to car truck side frames made from rolled,pressed or forged metal shapes.

The object of this invention, among other things, is to provide a lightand strong car truck side frame.

My invention consists of an improved car truck side frame wherein thecompression and tension members are integral with each other and thoseparts of the frame are made from rolled, pressed or forged metal incombination with a forged or cast open frame having sides acting asbolster guide bars.

In the accompanying drawing, Figure 1 is an end view of a channel. Fig.2 is a side view of Fig. 1 with dotted lines indicating where flangesare sheared and the top surface of the web of the channel is located.Fig. 3 is a bottom plan view of Fig. 2 slitted longitudinally with twolongitudinal slits. Fig. 4: is a side view of parts of my improved truckside frame. Fig. 5 is a top plan View of the part shown in Fig. 4. Fig.6 is a side view of my improved truck side frame showing its guideframe. Fig. 7 is a vertical. cross section of Fig. 6 on line A, A.

Like figures of reference refer to like parts throughout.

In the construction which I have shown as embodying my invention thecompression and tension members of the side frame are made from achannel 1 having parallel slits 6 in its web 3 which extendlongitudinally of said web 3 parallel to the flanges 5 of said channel 1and which terminate short of the ends of said web 3. The edges of theend portions of the flanges 5 are out off along oblique lines 4 so thatsaid flanges 5 taper at the ends of the channel 1. The middle portion ofthe web 3 bordered by the slits 6 and located between the ends 7 and 8of said slits 6 is displaced in a direction perpendicular to the planeof said web 3 to form an opening 9. In each of the end portions of saidweb 3 are holes 10 adapted to receive Specification of Letters Patent.

the bolts which secure the journal boxes to the side frame. In theopening 9 is fitted an open frame 12 in which there is an opening 15adapted to receive a bolster. The sides of the open frame 12 act asbolster guide bars and the open frame 12 will be termed a bolster guideframe. The bolster guide frame 12 has at its top two spaced flanges 16which engage the inside faces of the flanges 5 of the channel 1, and atthe top edge of each flange 16 is an auxiliary flange 17 which engagesover the top edge of one of said flanges 5. At the bottom of the bolsterguide frame 12 are two spaced flanges 18 which engage opposite edges ofthe middle portion of the web 8. Bolts 13 pass through the holes 11 in amiddle portion of the web 3 and hold the lower part of the bolster guideframe in engagement with said middle portion. The flanges 16 of thebolster guide frame 12 are fastened to the flanges 5 by rivets 14:.

Obviously, the particular construction which I have shown and describedmay be considerably modified without departing from my invention, and Ido not wisl1,therefore, to be limited to this exact construction.

What I claim as my invention is:

1. A car truck side frame made from a channel whose web has spacedlongitudinal slits therein terminating short of its ends, the middleportion of said web between said slits being displaced relatively to theremainder of said channel in a direction perpendicular to the plane ofsaid middle portion to form an opening, a one-piece frame mounted withinsaid opening and having an opening therein adapted to receive a bolster,said frame having spaced flanges engaging said middle portion of saidweb and the flanges of said channel, and means for fastening said frameto said middle portion of said web and to said flanges of said channel.

2. A car truck side frame made from a channel, whose web has two spacedlongitudinal slits therein terminating short of its ends, the middleportion of said web between said slits being displaced from theremainder of said channel in a direction perpendicular to the plane ofsaid middle portion to form an opening, an open frame mounted in saidopening and having sides acting as bolster guide bars, said frame havingflanges at the bottom straddling said middle portion of said Web andflanges at the top engaging the inside faces and tops of the flanges ofsaid channel, and means for fastening said frame to said middle portionof said Web and said flanges of said channel.

In testimony whereof, I have signed this specificationin the presence oftWo subscribing Witnesses.
